研究了插电式混合动力汽车用电池充电器的电感设计。该电感设计用于正在开发中的原型充电器(工作频率为250 kHz)的输入和输出部分。电路模拟表明，直流、60赫兹和500千赫时的电感电阻是决定电感效率的最主要因素。为了降低直流电阻，提出了基于平面母线堆叠的高密度绕组结构。为了降低交流阻抗，研究了准分布式间隙铁心结构。比较了具有E-E磁芯对的常规集中间隙结构和定制组装的准分布间隙磁心组。制作了每个样机，并用阻抗分析仪对其进行了表征。由母线绕组和准分布间隙结构组合而成的新样机在直流和500 kHz下表现出最佳的性能，因此是本文应用的最佳结构。
Inductor design is investigated for battery charger used in plug-in hybrid vehicles. The inductor is designed to be implemented at the input and output parts of prototype charger (operation at 250 kHz) under development. Circuit simulations revealed inductor resistances at DC, 60 Hz and 500 kHz are the most dominant factors determining inductor efficiency. To reduce DC resistance, high density winding structure based on planar busbar stacking is proposed. To reduce AC resistance, quasi-distributed gap core configuration is investigated. A conventional concentrated gap configuration with E-E core pair and a custom-assembled quasi-distributed gap core set are compared. Each prototype was fabricated and characterized with impedance analyzer. Our new prototype made by a combination of busbar winding and quasi-distributed gap configuration demonstrates the best performance at DC and 500 kHz, and thus, the best structure for the application herein.
